Despite advances in the design of automotive heat exchangers, the pressure is still strong for continued improvements, even in the face of demands for cost reductions. For evaporators, there are multiple needs, two of which are to reduce size and mass. Accomplishing this is a real challenge, since the cooling capacity and temperature uniformity should not be substantially compromised. Some designs presently in production accomplish this through increased complexity such as a multi-tank construction, adding fins on the refrigerant side, or manifold designs that utilize various sized orifices. Other designs presently in production use two-row extruded tube and center construction. While these designs have facilitated smaller heat exchanger design, the added complexity has increased the cost of producing the heat exchanger.
